V DOOR-STOP.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed December 26, 1918. Serial No. 268,288.

To all whom it may concern:

Be it known that I, NATHANIEL CRANK, citizen of the United States,residing at Hill City, in the county of Graham and State of Kansas. haveinvented certain new and useful Improvements in Door- Stops, of whichthe following is a specification.

This invention relates to door stops, and belongs to that class ofdevices for holding doors open against accidental displacement, suchdevices being customarily operated by the foot.

The object of this invention is the production of a door stop or holderhaving special construction and arrangement of its component parts,which is to be secured to the floor in the path of a door when opening,and which will be operated by the open. ing door to catch and hold thedoor, and. which may be released by the foot of the operator when it isdesiredto close the door. It i believed that a door stop made in accordance with this invention may be very cheaply manufactured, and at anunusually low cost.

The accompanying drawings set out the construction and arrangement ofthe parts of this invention as it is preferred to fashion and disposethem, and Figure 1 repre sents a side view of the lower corner portionof a door held open by the application of this invention. Fig. 2 is ahorizontal section of the door as shown in Fig. 1, and includes a planview of this invention holding the door in open position. Fig. 3 is ahorizontal section of the door as in Fig. 2, and shows the door swungpartly open, and illustrates the position of a door stop made inaccordance with this invention and which has been revolved horizontallyby the handor foot to release the door. Fig. 4 is a front view of a doorstop made in ad cordance with this invention. Fig. 5 is a top plan view.Fig. 6 is a side view. In Figs. 4, 5, and 6, the scale of drawings hasbeen increased to more clearly illustrate this invention.

Throughout the drawings and description the same letter is employed torefer to the same part.

Considering the drawings, the door A swings in the usual manner near thefloor a. Upon the floor is a floor plate B, usually circular in form,and riding upon the floor plate is a base plate 6 that is pivotallysecured upon the floor plate by means of a pivot pin 0.

hirected upon the base I) are two vertical a ls D and (Z. These wallsare customarily parallel as set forth, and they are joined at the bacl:by the rear wall E. As best shown in Fig. 4, the ends 'of the back orrear Wall E, marked F and f, extend outwardly beyond the ends 01": thevertical walls D and (Z and form wings projecting outwardly from thosewalls. Une among the advantages of having the wings F and 7 project wellbe yond the base plate and the floor plate as illustrated is that thestop is readily found and released by the foot in the darkness. Bysliding the foot along the lower edge of the door in contact with thefloor, the foot is guided directly against the proper wing and the stopreleased. The necessity for having two wings is to provide for doorswhich are swung to open in different directions, so. that one wing willalways project out-- wardly from the surbase of the wall of the room.

A. stop pin (5? limits the rotation of the base I) in one direction.

The operation of this invention is thought to be readily discerniblefrom the drawings and the foregoing description.

When the door stop is positioned upon the floor illustrated, and as setforth in Fig. 3, the door A may be swung in its opening movement so thatthe edge of the door will enter between the vertical walls, and thecontinued opening movement of the door will bring the door and the doorstop into the relative positions set forth in Fig. 2. N ow, the door isheld against displacement in either closing or opening directions. But,if the wing 7 be pressed upon by the foot of the operator, the base 5and parts carried thereby will be swung again into the positionsillustrated in Fig. 3, and the door may now be opened, and the door stopleft in the position for engaging the edge of the door when it is againopened.

Having now described this invention, and explained the mode of itsoperation, what I claim is The combination with a-fioor plate, of a baseplate pivotally mounted thereon, side walls erected upon the base plateand spaced apart, and a rear wall connecting the side walls, the ends ofthe rear wall projecting beyond the side walls for the purpose specifiedforming wings, and the said wings projecting beyond the base plate.

In testimony whereof I afiix my si NATHANIEL CR ature.
